The stereo outputs from the external tone generator module are connected to the AUX IN L and R jacks, allowing the sound of the tone generator to be reproduced via the Clavinova's internal sound system and speakers. 2 AUX OUT L/L+R and R Jacks The AUX OUT L/L+R and R jacks deliver the output of the Clavinova for connection to an instrument amplifier, mixing console, PA system, or recording equipment. If you will be connecting the Clavinova to a monaural sound system, use only the L/L+R jack. When a plug is inserted into the L/L+R jack only, the left- and rightchannel signals are combined and delivered via the L/L+R jack so you don't lose any of the Clavinova's sound. q The Internal Amplifier & Speaker System The CLP-311 features a high-performance stereo amplifier delivering 20 watts per channel to a pair of 16-cm speaker units. NOTE • The AUX OUT jack signal must never be returned to the AUX IN jacks, either directly or through external equipment. 3 MIDI IN and OUT Connectors The MIDI IN connector receives MIDI data from an external MIDI device (such as the DOU-10 Disk Orchestra Unit) which can be used to control the Clavinova. The MIDI OUT connector transmits MIDI data generated by the Clavinova (e.g. note and velocity data produced by playing the Clavinova keyboard). More details on MIDI are given in "MIDI FUNCTIONS" on page 13. q PHONES Jacks (Bottom Panel) Two pairs of standard pair of stereo headphones can be plugged in here for private practice or late-night playing. The internal speaker system is automatically shut off when a pair of headphones is plugged into either of the PHONES jacks. 4
